What is the difference between F-14A and F-14B and which buttons to assign?

[ASW]

I finally got to the F-14A, but I didn't understand how it differs fundamentally except for the engines and the scales of the engine operation and fuel consumption in the cockpit. Guys, who knows, tell me how else these planes differ and which buttons on the joystick and keyboard are important for the F-14A. I am grateful in advance.

The difference between the our F-14B and the F-14A blk 135 are... the engines, the engine gauge, and the A doesn't have the thrust asymmetry limiter / SEC panel the B does. Otherwise major systems (RWR, RADAR, Navigation, etc.) are all the same. This is, btw, why the B was originally called the A+, it was just intended to be an up engined A as an interim measure until the D could enter service in numbers. 

Control mappings should be common between the two aircraft, so you shouldn't even need to remap anything.

Eventually HB should be giving us an older F-14A variant for the USN and the IRIAF each. Those should have some more noticeable differences, especially regarding the RWR.

The A+ came with the AN/ALR-67, this would come quite some time later for A’s. Which is obviously a great leap over the existing AN/ALR-45/50 and I believe all A+‘s had all the upgrades that were spread across the fleet from the factory whereas most A’s where a huge mismatch of existing gear.

Only F-14A specific keybinding you might need is the mid compression bypass switch. Might or might not be helpful if you're flying a TF-30 equipped F-14.

And what exactly does it give? What is the result? And where is he in the cockpit?

From one of HB's dev updates about the F-14A:
"In order to reduce pressure distortions at the compressor face,[the mid compression bypass] system ports air from the low pressure compressor into the fan bypass duct. This increases the quality of the air downstream and greatly reduces the chance of a compressor stall. However, it comes at a cost of about 3000 lbf (13344 N) of thrust per engine when active. It is activated in several scenarios where you likely need thrust the most; Zone 5 AB while the gear handle is down (takeoffs, wave-offs, and bolters), High AOA flight, and when large rudder commands are being applied. It also activates during gun firing and aerial refueling operations to reduce the chance of stall from ingesting gun gas or jet wash."

It basically gives more thrust under certain conditions.

I don't think it's currently modelled in the cockpit as a pullable circuit breaker and is only usable as a keybind.

I use a translator, but I understood the main idea. This is an increase in traction. Is it somehow displayed on the engine operation devices? I assigned the Mid compression bypass CB Pull CF-30 button only, but I didn't see any difference.

In most cases you won’t notice a change.

Try not to think of the MCB circuit breaker as “giving” you more thrust. The TF-30s make about 17,000 lbs of thrust each, normally. While the MCB is open they make about 14,000 lbs each and that will happen under a handful of conditions listed above but it’s generally only open for a few seconds at a time. There’s a circuit diagram in the NATOPS detailing all the conditions and timers.

Anyway, pulling that breaker just prevents that drop in thrust under those conditions but may lead to engine stalls.
